When reading her post, I immediately thought of Glenn Beck. I think he is in a special category all his own. He is both a manipulative non-believer, who seems to be stupid enough to be buying into his own con. One image jumped to mind:
For those of you who have not seen Tropic Thunder, go see Tropic Thunder. The premise of this scene is simple: Ben Stiller was an actor in a terrible movie, but in this isolated spot he has an audience that loves his re-enactments of this movie. In his audiences adoration for his performance, he loses his self identity.
To me, this happens to conservative pundits. They don't really believe what they're shilling at first. But, pretty soon the applause of their audience carries them away, and they actually believe it.
